With up to 80 small, atentaculate marginal swellings or warts. All marginal bulbs and warts without keel, but with excretory papillae adaxially; lateral cirri present. Manubrium short, flask-shaped, not connected to radial canals by mesenteries. Mouth simple, quadrate, with four short, slightly crenulated lips (damaged in specimens on hand).
